Frequency bands
Quad band: GSM 850/900/1800/1900MHz
GSM class
Small MS
Output power (according to
Release 99, V5)
Class 4 (+33dBm ±2dB) for EGSM850
Class 4 (+33dBm ±2dB) for EGSM900
Class 1 (+30dBm ±2dB) for GSM1800
Class 1 (+30dBm ±2dB) for GSM1900
XT75 only:
Class E2 (+27dBm ± 3dB) for GSM 850 8-PSK
Class E2 (+27dBm ± 3dB) for GSM 900 8-PSK
Class E2 (+26dBm +3 /-4dB) for GSM 1800 8-PSK
Class E2 (+26dBm +3 /-4dB) for GSM 1900 8-PSK
The values stated above are maximum limits. According to Release 99, the max-
imum output power in a multislot configuration may be lower. The nominal reduc-
tion of maximum output power varies with the number of uplink timeslots used
and amounts to 3.0dB for 2Tx, 4.8dB for 3Tx and 6.0dB for 4Tx.
